DESCRIPTION
1.1A, 35MHz Current Feedback Amplifier The LT®1210 is a current feedback amplifier with high output current and excellent large-signal characteristics. The combination of high slew rate, 1.1A output drive and ±15V operation enables the device to deliver signifi- cant power at frequencies in the 1MHz to 2MHz range. Short-circuit protection and thermal shutdown ensure the device’s ruggedness. The LT1210 is stable with large capacitive loads, and can easily supply the large currents required by the capacitive loading. A shutdown feature switches the device into a high impedance and low sup- ply current mode, reducing dissipation when the device is not in use. For lower bandwidth applications, the sup- ply current can be reduced with a single external resistor. The LT1210 is available in the TO-220 and DD pack - ages for operation with supplies up to ±15V. For ±5V applications the device is also available in a low thermal resistance SO-16 package. T wisted Pair Driver

VCM = 0V, ±5V ≤ VS ≤ ±15V, pulse tested, VSD = 0V, unless otherwise noted. Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: A heat sink may be required to keep the junction temperature below the Absolute Maximum rating. Applies to short circuits to ground only. A short circuit between the output and either supply may permanently damage the part when operated on supplies greater than ±10V. Note 3: The LT1210C/LT1210I are guaranteed functional over the temperature range of –40°C to 85°C. Note 4: The LT1210C is guaranteed to meet specified performance from 0°C to 70°C. The LT1210C is designed, characterized and expected to meet specified performance from –40°C to 85°C but not tested or QA sampled at these temperatures. The LT1210I is guaranteed to meet specified performance from –40°C to 85°C. Note 5: SO package is recommended for ±5V supplies only, as the power dissipation of the SO package limits performance on higher supplies. For supply voltages greater than ±5V, use the TO-220 or DD package. See Thermal Considerations in the Applications Information section for details on calculating junction temperature. If the maximum dissipation of the package is exceeded, the device will go into thermal shutdown. Note 6: RSD is connected between the Shutdown pin and ground. Note 7: Slew rate is measured at ±5V on a ±10V output signal while operating on ±15V supplies with RF = 1.5kΩ, RG = 1.5kΩ and RL = 400Ω. Note 8: NTSC composite video with an output level of 2V.

Rev CFor more information www.analog.com APPLICATIONS INFORMATION The LT1210 is a current feedback amplifier with high out- put current drive capability. The device is stable with large capacitive loads and can easily supply the high currents required by capacitive loads. The amplifier will drive low impedance loads such as cables with excellent linearity at high frequencies. Feedback Resistor Selection The optimum value for the feedback resistors is a function of the operating conditions of the device, the load imped- ance and the desired flatness of response. The Typical AC Performance tables give the values which result in less than 1dB of peaking for various resistive loads and oper- ating conditions. If this level of flatness is not required, a higher bandwidth can be obtained by use of a lower feedback resistor . The characteristic curves of Bandwidth vs Supply Voltage indicate feedback resistors for peak - ing up to 5dB. These curves use a solid line when the response has less than 1dB of peaking and a dashed line when the response has 1dB to 5dB of peaking. The curves stop where the response has more than 5dB of peaking. For resistive loads, the COMP pin should be left open (see Capacitive Loads section). Capacitive Loads The LT1210 includes an optional compensation network for driving capacitive loads. This network eliminates most of the output stage peaking associated with capacitive loads, allowing the frequency response to be flattened. Figure 1 shows the effect of the network on a 200pF load. Without the optional compensation, there is a 6dB peak at 40MHz caused by the effect of the capacitance on the output stage. Adding a 0.01µF bypass capacitor between the output and the COMP pins connects the compensation and greatly reduces the peaking. A lower value feedback resistor can now be used, resulting in a response which is flat to ±1dB to 40MHz. The network has the greatest effect for CL in the range of 0pF to 1000pF. The graphs of Bandwidth and Feedback Resistance vs Capacitive Load can be used to select the appropriate value of feedback resistor . The values shown are for 1dB and 5dB peaking at a gain of 2 with no resistive load. This is a worst-case con- dition, as the amplifier is more stable at higher gains and with some resistive load in parallel with the capacitance. Also shown is the –3dB bandwidth with the suggested feedback resistor vs the load capacitance. Although the optional compensation works well with capacitive loads, it simply reduces the bandwidth when it is connected with resistive loads. For instance, with a 10Ω load, the bandwidth drops from 35MHz to 26MHz when the compensation is connected. Hence, the com - pensation was made optional. To disconnect the optional compensation, leave the COMP pin open. Shutdown/Current Set If the shutdown feature is not used, the SHUTDOWN pin must be connected to ground or V–. The Shutdown pin can be used to either turn off the bias- ing for the amplifier , reducing the quiescent current to less than 200µA, or to control the quiescent current in normal operation. The total bias current in the LT1210 is controlled by the current flowing out of the Shutdown pin. When the Shutdown pin is open or driven to the positive supply, the part is shut down. In the shutdown mode, the output looks like a 70pF capacitor and the supply current is typi- cally less than 100µA. The Shutdown pin is referenced to the positive supply through an internal bias circuit (see the Simplified Schematic). An easy way to force shutdown is to use open-drain (collector) logic. The circuit shown in Figure 2 uses a 74C906 buffer to interface between 5V logic and the LT1210. The switching time between the active and shutdown states is about 1µs. A 24kΩ pull-up Figure 1.

The device dissipation can be found by measuring the supply currents, calculating the total dissipation and then subtracting the dissipation in the load and feed - back network.
